Table 3 Changes in IEC-18 Cell Viability (MTT Assay) in Response to Oxidants and the Effects of Dietary Antioxidants

From: Dietary antioxidants protect gut epithelial cells from oxidant-induced apoptosis

Treatment Agonist Agonist + Cat's claw Agonist + Green tea Agonist + Vitamin C
H2O2 102.3 ± 2.3 105.8 ± 2.3 123.1 ± 3.7 99.9 ± 2.4
Peroxynitrite 76.9 ± 1.9 79.7 ± 2.5 85.6 ± 2.2 90.5 ± 2.2
DPPH 70.4 ± 1.3 74.2 ± 2.5 79.7 ± 1.8* 69.5 ± 1.4
  1. Viability was determined by the MTT assay and results are expressed as a percentage of control values (Mean ± SEM), N = 6 in each group. The * indicates a significant improvement in cell viability when compared to agonist alone (P < 0.05).
